#Script to detect hardlink in the file system from the current directory
#Bertrand VANDEPORTAELE 2016
#inspired from http://superuser.com/questions/485919/how-can-i-find-all-hardlinked-files-on-a-filesystem
#run this script from the folder where you want to detect the files 
#this script has to be run as sudo in order to recurse inside directory with restricted read access
 
#find ./ -type f -printf '%n %p\n' | awk '$1 > 1{$1="";print}'
#to display the inode number and the number of hardlinks for each inode
#find ./ -type f -links +1 -printf '%i %n %p\n'  
#to sort by inode number and thus regroup harlinks to similar inode
find ./ -type f -links +1 -printf '%i %n %p\n' | sort -n -k 1
